Version 2019-12-12

The 2019-12-12 Azure Storage version includes the following features and updates:

• Two new APIs, Get Blob Tags and Set Blob Tags, allow user-defined tags to be added to a blob, which then act as a secondary index.

• A new API, Find Blobs by Tags, allows blobs to be retrieved based on their tags.

• A new API, Query Blob Contents, applies a simple Structured Query Language (SQL) statement on a blob's contents and returns only the queried subset of the data.

• A new API, Restore Container, supports soft deletion of containers.

• The Set Blob Tier API can now be called on snapshots.

• The maximum size of a block that can be uploaded via Put Block has been increased to 4 gibibytes (GiB), or 4000 mebibytes (MiB). This means that the maximum size of a block blob is now approximately 200 tebibytes (TiB).

• The maximum size for a blob uploaded through Put Blob has been increased to 5 GiB, or 5000 MiB.

• Static website settings now support an absolute path for the index document.

• Azure Blob Storage and Azure Queue Storage anonymous and OAuth requests return 401 (Unauthorized) with identity provider and resource information to support bearer challenge.

• Blob APIs now support the Blob Versioning feature, which provides a fixed way to access a blob in subsequent requests.
